*FL-DATING* WEATHER- STRIP.

T0 all whom t may concern Be it` known that I, JOHN W. HAD/rains, acitizen of the United States, and resident of Racine, in the county ofRacine and State of Wisconsin, have invented certain new and usefulImprovements in Floating Weather Strips; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention refers to weather strips for swinging doors, windows or thelike, the primary object being to provide a simple, economical andpositively acting weather strip of a yielding rolling type, whereby thejoint between the door or window and the frame is in elect hermeticallysealed, and variations in the width of the gap to be sealed areautomatically taken up, so as to materially increase the life of thestrip.

ith the above and other minor objects in view, the invention consists incertain peculiarities of kconstruction and combination of parts, as arehereinafter set forth with reference to the accompanying drawn 1 ingsand subsequently claimed.

In the drawings:

Figure 1 represents a side elevation of the bottom of a swinging doorequipped with a rolling weather strip structure embodying the featuresof my invention.

Figure 2 is a cross section of the' same, the section being indicated byline 2v2' of Figure l.

Figure 3 is an end elevation of the door showing a retainer plateemployed in connection with my improved weather strip structure.

Referring by characters to the drawings, with especial reference toFigures l to 3, A represents the bottom portion of a door provided witha longitudinal cavity B. The end edges of the cavity are formed withupwardly extended narrow channels 0, which serve as pockets for parts ofa retainer plate l. Each retainer plate is secured to an end edge of thedoor, whereby the cavity and channel are closed. The plate is formed inthis instance with an inturned apertured ear 2, for the reception of aguide plunger 3, which guide plunger is secured to a projection that isformed upon an apertured ear bracket 4. The ear bracket is arranged toslide upon the inner surface of the plate Specification of LettersPatent.

1921. Serial No. Al'l l, and the aperture thereof forms a journal forthe pintle 5 of a yieldable roller 6. The roller may be formed with acentral core which is jacketed by an outer cover or tube of rubber, oranalogous material, as best shown in Figure 2 of the drawings, it beingunderstood that the jacket can be replaced when worn down from wear by asimple operation.

It is also understood that each of the plate members for retaining theroller are similarly arranged in connection with the door.

'Ihus it will be seen that the roller may ride and fall upon the flooror opposed wall to compensate for any irregularities there-- in and`said roller, due to its projection slightly below the bottom of thedoor, forms a sealing element for the gap developed 'between the bottomedge of said door and the opposed fixed surface. ln practice it has beenfound that while the engagement between the roller and floor line willseal the gap at this point. there is a certain lateral play necessary,whereby a more or less minute gap will develop between the surface ofthe rod 6 and the inner walls of the cavity B, Hence, in such cases airand dust will not be excluded as they are free to pass between the wallsof the cavity and the peripheral edges of the roller.

In order to overcome this leakage, I provide an auxiliary floating rodwhich is loosely fitted into the cavity and arranged to rest upon theupper surface of the roller. This rod may be in the form of a roundroller, or polygonal in shape, and it extends from end to end of thecavity, whereby the gap is sealed, due to the fact that when the rollturns in either direction, this {loating` auxiliary rody or roller willdrop against one of the side walls of the cavity and thus seal the gapwhich would otherwise be free to permit a current of air to travel upand about the main roller 6.

`While I have shown and described two forms of my invention` whichembody the broad features. obviously I may vary these details ofconstruction within the scope of the claim.

I claim:

In a swinging closure having a longitudinally disposed cavity in itsedge, a yieldu able floating roller mounted in the cavity and tending totravel therethrough are cheeked. adapted to engage an opposed iXedAsurface ln testimony that I claim the foregoing to 'seal the gapbetween the iXed surface I have hereunto set my hand at lIilWaukee, l0and the movable closure the combination in the county of Milwaukee andState of 5 of an auxiliary strip associated with the Wisconsin ioat-ingroller for engagement with the innery 1 Walls of the cavity, wherebycurrents ofk air JOHN W.
